Income Taxes	Note 10. Income Taxes Income tax expense relates principally to operating results of foreign entities in jurisdictions, primarily in Europe and Asia, where the Company earns taxable income. The Company has significant net operating losses in the United States and certain other tax jurisdictions and, as a result, does not pay significant income taxes in those jurisdictions. At December 31, 2015, the Company had $124.2 million of deferred tax assets worldwide relating to net operating loss carryforwards, tax credit carryforwards and other temporary differences, which are available to reduce income taxes in future years. The Company maintains a 100% domestic valuation allowance reducing the carrying value of the deferred tax assets in the United States to zero. The Company will continue to maintain a full valuation allowance for those tax assets until sustainable future levels of profitability are evident. During the first quarter of 2016, the statute of limitations associated with a tax position previously taken by the Company expired. This previously recorded tax reserve of $0.6 million and related accrued interest of $0.3 million was reversed during the three months ended March 31, 2016.
